This study presents a comprehensive design of a beam-steering two-dimensional antenna array, utilizing a Butler Matrix 4 × 4 as a feed network for X-band applications. The simulated system operates within the X-Band frequency range. Accurate beam steering at +10°, -37°, +37°, and -10° angles is realized, allowing for wide angular coverage. The design exhibits a gain of around 17.7 dBi. Due to cost-effective fabrication and easy implementation, the antenna system can be implemented in next-generation wireless communication and radar systems.
